Study population: In this cross-sectional case-control study, PA was investigated in all patients with PTC and EH (n= 137), regardless of hypertension severity, under active surveillance at a cancer institute from 2019 to 2022. The control group included 137 (1:1) age-, sex- and body mass index (BMI)-matched individuals from a retrospective cohort of EH previously investigated for PA from 2011 to 2022. Serum aldosterone and plasma direct renin concentrations were measured by a chemiluminescent immunoassay. A positive PA screening was defined by aldosterone > or = 10 ng/dL and aldosterone to renin ratio > or = 2 ng/dL/uUI/mL.

Who may be able to join

  • All patients with PTC and EH regardless of hypertension severity

Who cannot join

  • Patients who were using medications that secondarily increase blood pressure levels were excluded
  • Did not agree to participate

About this study

Aldosterone excess can cause oxidative stress leading to DNA damage in vitro and in vivo. Single case reports demonstrated a coincidence of primary aldosteronism (PA) with different malignancies. A higher prevalence of thyroid nodules and non-toxic multinodular goiter was described in patients with PA compared to those with essential hypertension (EH). A single study showed an association between PA and papillary thyroid cancer (PTC), but without a paired control group. Objective: To assess PA prevalence in a transversal cohort of patients with PTC and EH compared to a paired control group with HT.

Read the detailed description

Primary aldosteronism (PA) is the most frequent cause of endocrine hypertension, with an estimated prevalence of 20% among individuals with resistant hypertension. PA is associated with an increased risk of malignancy, probably due to aldosterone effects in promoting cell proliferation. Recently, a high prevalence of PA was demonstrated in patients with essential hypertension (EH) and papillary thyroid cancer (PTC), similarly to the prevalence of PA among individuals with resistant EH. In addition, abnormalities in thyroid ultrasound (non-toxic multinodular goiter) are more common in PA patients when compared to controls. Despite of this initial evidence, the link between PA and PTC remains to be elucidated. Then, the aim of this study is to investigate the clinical and genetic aspects of the association between PA and PTC. The specific aims are: 1) To evaluate the prevalence of PA in a transversal cohort of patients with EH and PCT; 2) To investigate thyroid ultrasonography abnormalities in PA patients; 3) To perform exome sequencing (blood DNA) in patients with PA and PTC paired with tumor tissue; and 4) To conduct functional studies of the novel genetic variants identified by exome sequencing. To achieve this goal, the investigators will employ the following techniques: next-generation sequencing, bioinformatic analysis, real-time PCR and immunohistochemistry. In this project, the investigators expect to establish the prevalence of PA among patients with EH and PTC, and to identify new genetic targets involved in the association between PA in PTC.

Questions about this trial

What is this clinical trial studying?

An observational study of Thyroid Cancer, Papillary and Primary Aldosteronism, run by Instituto do Cancer do Estado de São Paulo at 1 site in Brazil.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 5 Oct 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

PA prevalence in a transversal cohort of patients with PTC and EH (time frame: Through study completion, an average of 1,5 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Oct 2023.
